Content preview: Markus - I looked at the audio coming out of my sound card using Opera 2 and certainly the keying on waveform, in my opinion is pretty fast rise and the click is very tangible In fact what I see is for shorter keying periods the key on rise is slower - but if theres a substantial gap the next audio tone on is very harsh and the key click hits the audio agc very hard.. Now, this may be my sound card, but turning levels down doesnt appear to change the ramp up rate at key on looking on the scope. I dont get the same with other keyed audio tone problems that have a more softkeying ramp. Just my observation here, wonder if it can be made a little softer if its more than my local conditions here. Over the pole wise Im still seeing nothing from Europe and only the first tinges of DCF39 being visible at dot 60 slow - just.
